sin theta × cos (90-theta )+1/2+tan^2 theta
sin theta ×sin theta +1/sec^2theta. {1+tan square theta =sec square theta }
sin^2theta +1/sec^2 theta
cos^2 theta / 1/cos ^2 theta { sec square theta= 2/ cos square theta}
= cos^4 theta
sin theta ×sin theta +1/sec^2theta. {1+tan square theta =sec square theta }
sin^2theta +1/sec^2 theta
cos^2 theta / 1/cos ^2 theta { sec square theta= 2/ cos square theta}
= cos^4 theta
